Robison Family line

Got sidetracked, I started going through my family tree, sometimes when I am tired at night, that is what I do, just walk through the different family lines.  I found 2 that need some serious work done to it.  Lots of information on ancestry.com is wrong, places of birth/death.  Can make for finding absolutely nothing which is what it was doing till I changed it.  Very different findings I am finding for my cluster research of this family.  This is going to take some very intense work because I am finding dates and places both wrong on all accounts that I find people have already listed.
